RECOMMENDATION:
Introduce and give first reading to ordinance to amend Title 12 of the Costa Mesa
Municipal Code, Chapter II, Article 1, Section 12-20 .to establish a new section
prohibiting lake fishing and human water contact at TeWinkle Park Lakes, and to
amend Title 12 of the Costa Mesa Municipal Code, Chapter II, Article 1, Section 12-20
(18) to prohibit the feeding of fowl at TeWinkle Park.
BACKGROUND:
At the Parks and Recreation Commission meeting of September 22, 2010, the
Commission unanimously approved two recommendations to the City Council to
implement a prohibition of fishing and human water contact; and to prohibit the feeding of
water fowl at the TeWinkle Park. Lakes.
At the City Council meeting of May 20, 2002, the Council adopted Ordinance 02-10,
Amending Title 12 of The Costa Mesa Municipal Code Section 12-20(18) to prohibit the
feeding of wild animals in City parks, while at the same time removing from. the prohibition
the feeding of wild fowl in TeWinkle Park. The change in ordinance was intended to
address the many issues created by well meaning park patrons that come to City parks
daily and pour large quantities of bread or other food stuffs on the ground to feed
pigeons, ducks, geese, etc. This food source results in growing population of resident
pigeons, ducks, geese and unintentional increases in ground squirrel, rat, and skunk
populations. On a daily basis, patrons have been observed discarding a wide variety of
leftover food, which decomposes and creates an unsightly and unhealthy mess in the
parks.
During construction and upon completion of the renovation of the TeWinkle Park Lakes in
May 2006, City staff noted the potential vulnerability of the circulation and aeration .
systems to damage from park patrons entering the lakes and the impacts of fishing lines
possibly becoming entangled in the underwater lines. At that time, it was decided not to
- attempt implementing. a ban on fishing or human contact with the lake water. This was
based on the assumption by staff -that the popularity of these activities over a long period
of time in the past would make restricting them unpopular and very difficult to find support
for with the Parks and Recreation Commission and City Council without some definitive
evidence supporting the contention that the lake systems could be damaged as a result of
them..
The overall appearance and water quality of the lakes depends heavily on a water
circulation system delivered through large PVC piping laid on the lake bottom throughout
the lakes and weighted ozone/aeration tubing laid on the lake bottom in key locations.
The circulation lines and nozzles are just below the surface in many locations and are
vulnerable to damage both intentional and unintentional. Similarly, the aeration lines are
vulnerable to being snagged by fishing lines. These lines are weighted softer plastic
lines.
Over the past few years, nylon fishing lines have proven to be very damaging to the lake
circulation and aeration lines. When anglers snag the piping or aeration lines and -then
pull to recover their tackle, sub -surface circulation pipes have been broken and aeration
lines have been dislodged from their shore based air/ozone supply lines. This may also
be caused by park patrons that recreate inside the lakes themselves and step on the
lines. Unfortunately, the resulting breaks in the circulation lines are several feet below the
surface of the water and are not repairable without totally draining the lakes, at a
significant cost in replacement water. The broken lines compromise the integrity of the
circulation system and have resulted in a decline in overall effectiveness.
Over the course of several months thisyear, it became apparent that the water circulation
in the lakes was well below what was observed in the first few years of operation. With
poor water circulation, City staff and the public have noticed the accumulation of trash
and debris in some locations and a dramatic increase in algae growth. The overall
decrease in the effectiveness of the existing lake systems required the use of chemicals
to manage algae growth at acceptable levels. With poor circulation and the constant
addition of fecal matter from overfed water fowl, the battle against algae blooms became
very challenging. Additionally, without proper circulation and aeration, the natural
decomposition systems in the lake do not break down the high nutrient load of the fecal
matter generated by the excess feeding of the water fowl. This leads to poor water
quality and elevated bacteria levels.
The combination of algae and high bacteria levels could make the water a potential health
hazard, and certainly unsuitable for public contact. There is no water sanitizing system
incorporated into the lake management equipment. This potential health hazard reduces
the overall quality of the lakes, negatively impacts the enjoyment by patrons, and creates
a significant liability for the City, should any serious illness attributable to the lakes occur.
In June 2010, with one of the large circulation pumps experiencing significant problems,
the decision was made to remove the two large pumps and inspect them for damage.
The damage to the pumps from debris entering them was significant and costly to repair.
The lake circulation systems were non -operational for approximately six weeks and the
total cost of repairs was in excess of $28,000. During the `down time' for pump repairs,
feasible repairs of circulation systems, aeration/ozone systems, lake leaks and other
items were completed. Unfortunately there were some repairs that could not be
completed due to the high cost and the necessity to drain the lakes to make them. To
keep the lakes operational and prevent greater expenditures, the leaking east upper
water fall was deactivated; the automatic lake fill line was re-routed, and attempts were
made to improve the integrity of the upper lake to reduce unmanaged water flow into the
lower lake. At that time, significant amounts of contract labor were utilized to clean the
2
lower lake bio -filter and remove as much algae growth and debris as possible from all the
lakes.
ANALYSIS
Fishinq:
With the pumps completely renovated and reinstalled, water circulation has improved.
There is funding in the FY 2010-11 Capital Improvement Program budget to install three
aerating fountains and to replace the aeration/ozone system with a more effective
aeration system. It is anticipated that these expenditures will increase the oxygen levels
in the lake water, promoting improved aerobic decomposition of fecal matter on the lake
bottom and aiding in the efforts to reduce algae development, and bacteria levels. The
new aeration system was installed within the past two weeks. The fountains are
anticipated to be installed before the end of the year.
With nearly $40,000 already spent on restoration to damaged lake systems; and another
$70,000 of budgeted improvements underway, it is vital for the health of public, the lake
and to control maintenance costs that a ban on., fishing and public water contact be
implemented. The aeration lines, electrical supply lines and the motorized fountains
could be damaged by fisherman pulling on them. Damage of this nature is not covered
by manufacturer warranties.
Feeding Waterfowl:
The overfeeding of water fowl, both domesticated and wild, has resulted in a dramatic
increase of non -migrating fowl. This population has destroyed all, the shrubs and colorful
landscape plantings that were added to the lake renovation project; has increased the
pollution of the water and the surrounding turf areas with excessive fecal material; and
created a potential public safety hazard; an unnatural and unhealthy reliance by the fowl
on low nutrition food sources (bread) that are detrimental to the health and mobility ,of the
wild fowl. Additionally, with easily available food, the wild birds tend to remain and breed
with domesticated fowl; becoming non -migratory. To address public safety, wild fowl
health, as well as to provide a relaxing and beautiful environment to public, the prohibition
of feeding wild life is essential. Currently there are signs around the lakes with
educational information attempting to convey to park patrons the negative impacts of
feeding wild fowl. The signs appear to have had limited impact on the problem.
ALTERNATIVES CONSIDERED
Council could prohibit only fishing.
2. Council could prohibit only the feeding of water fowl; both wild and domesticated.
3. Council could take no action to amend the Municipal Code as it relates to the lakes at
TeWinkle Park.
FISCAL REVIEW
There are no direct fiscal impacts related to the recommended Municipal Code
amendments. However, there may be a reduction in future maintenance and repair costs
3
associated with lake circulation and aeration systems if the recommended code changes
are effective in reducing equipment damage and improving water quality. There would be
minor costs associated with manufacturing and installing prohibition signs. There may be
unknown costs associated with enforcement of new regulations.
LEGAL REVIEW
The City Attorney has reviewed this item and has prepared an appropriate draft
ordinance for Council consideration based on staff recommendations.
CONCLUSION
The continuous fishing over the past few years has resulted in significant damage to the
lake aeration system, creating a potential safety hazard to the public as well as causing
unnecessary and preventable maintenance costs. The prohibition of fishing will reduce
the damage to the circulation systems in the lakes and support the overall management
goals of improving the lake water quality without the use of chemicals.
Although feeding wild and domesticated animals at TeWinkle Park Lakes appears to be a
harmless activity for park visitors, it contributes to the over population and declining health
of the animals and increases the pollution of the lakes. Restricting the feeding of water
fowl will improve the overall water quality of the lakes and encourage a more wild
population of migrant birds, rather than providing 'an abundant source of low nutritional
value foods, which ultimately increases the fecal material in the lakes.
Both recommendations will support the fundamental concept of creating and maintaining
a healthy sustainable lake and the associated population of wildlife. The result will be a
more aesthetically pleasing park and lake setting for residents and visitors to enjoy.

CALIFORNIA AMENDING SECTION 12-20 "DISORDERLY
CONDUCT" OF ARTICLE 1 "GENERALLY" OF CHAPTER II
"USE REGULATED" OF TITLE 12 "PARKS AND
RECREATION" OF THE COSTA MESA MUNICIPAL CODE TO
PROHIBIT FISHING AND FEEDING OF WILD FOWL IN CITY
PARKS
THE CITY COUNCIL OF THE CITY OF COSTA MESA HEREBY RESOLVES AS
FOLLOWS:
WHEREAS, the overall appearance and water quality at TeWinkle Park lakes depends
heavily on a water circulation system delivered through large PVC piping laid on the lake
bottom throughout the lakes and weighted ozone/aeration tubing laid on the lake bottom in key
locations; and
WHEREAS, the aeration lines are vulnerable to being snagged by fishing lines and over
the past few years, nylon fishing lines have proven to be very damaging to the lake circulation
and aeration lines when anglers snag the piping or aeration lines and then pull to recover their
tackle resulting in large decreases in the overall effectiveness of the water circulation and
aeration systems; and
WHEREAS, the decrease in effectiveness of the water circulation and aeration systems
has been observed to cause increased accumulation of trash and debris in some locations and
a dramatic increase in algae growth; and
WHEREAS, well meaning visitors to TeWinkle Park Lakes pour large quantities of
bread and other foodstuffs on the ground for the feeding of pigeons, ducks, geese, and other
fowl, and said food being left on the ground has been observed to decompose and leave
unsightly and unhealthy messes, and serves to attract a growing population of rats, skunks,
and ground squirrels; and
WHEREAS, the increased populations of rats, skunks, and ground squirrels contribute
inordinate amounts of fecal matter into the lakes at the same time the lakes suffer from
decreased efficiency of the water circulation and aeration systems compromises the lakes'
ability to decompose the fecal matter, increases poor water quality, and causes elevated
bacteria levels, and aggressive algae growth; and
WHEREAS, the water circulation and aeration systems remain vulnerable to fishing and
human water contact; and
WHEREAS, the overfeeding of waterfowl, both domesticated and wild, has resulted in a
1
dramatic increase of non -migrating fowl resulting in damage to landscaping, increased pollution.
of the lakes and surrounding turf areas, creating a potential public health hazard; and
WHEREAS, existing signs around the park educating visitors on the negative impact of
feeding wild fowl, appears to have insufficient impact to deter the negative effects of this
behavior; and
WHEREAS, the existing prohibition on feeding wild fowl should be extended to include
TeWinkle-Park; and -a -ban -on -fishing -should -be -adopted; and
WHEREAS, adoption of this amendment will prohibit the feeding of wild fowl at
TeWinkle Park and fishing in TeWinkle Park Lakes thereby protecting the efficiency of the
water and aeration systems and avoiding a potential human health hazard.
